Abstract: The present document relates to methods and apparatus for rendering input audio for playback in a playback environment. The input audio includes at least one audio object and associated metadata, and the associated metadata indicates at least a location of the audio object. A method for rendering input audio including divergence metadata for playback in a playback environment comprises creating two additional audio objects associated with the audio object such that respective locations of the two additional audio objects are evenly spaced from the location of the audio object, on opposite sides of the location of the audio object when seen from an intended listener's position in the playback environment, determining respective weight factors for application to the audio object and the two additional audio objects, and rendering the audio object and the two additional audio objects to one or more speaker feeds in accordance with the determined weight factors.

Abstract: The invention relates to a deployable probe for measuring fluid pressures such as pitot and/or static pressure. The probe comprises an outer tubular casing, a probe member telescopically extendible from within the outer casing, spring means urging the probe member to extend longitudinally from an undeployed position which is wholly contained within the outer casing, a latch retaining the probe member in the undeployed position and releasable to deploy the probe, and extendible communicating means interconnecting the probe member and the outer tubular casing for supplying pressure indications from the probe member when the probe is deployed.
